The course teaches the basics of static electric and magnetic fields in vacuum, starting with Coulomb’s force law for charges.
Electromagnetism is important for understanding nature, and is essential for the study of science, engineering, life sciences, and other specialized courses. Students will understand how electric and magnetic fields are produced by charges and current, respectively, and their mathematical descriptions. This will allow them to understand static electromagnetic phenomena as well as allow them to solve basic problems in electromagnetism.
By completing this course, students will be able to:
1) Understand the concepts of electric field, electric potential, electrostatic energy, magnetic flux density, magnetic moment, etc., correctly, and describe them mathematically.
2) Understand Gauss's law for electric fields and the Biot-Savart law for magnetic fields correctly, and find the electric field and magnetic flux density by applying said laws.
3) Find mathematical solutions to problems in electromagnetism expressed by the appropriate equations, and explain the physical meaning of said solutions.
